Infectious disease quadruple test can usually produce results in 4~24 hours, depending on the hospital. Infectious disease test includes Hepatitis B surface antigen, Hepatitis C antibody, Syphilis spirochete antibody and AIDS antibody, which are mainly for screening the presence of infectious diseases. Some patients may not have any symptoms after infection or may be in the early stage of infection, which needs to be detected through physical examination, and can better diagnose the disease. These four infectious diseases can be transmitted through blood, sexual contact, and mother-to-child transmission, and the examination can be done in time to isolate the disease and avoid indirect transmission. It is best to take the test on an empty stomach to ensure the accuracy of the results, and the results are usually available on the same day.
